Ah, RAIV style copy camshaft. Rhodes lifters would provide some additional low end torque. The best way to increase power everywhere for a given cam and engine size is to increase compression to the limit of the available octane. Rhodes lifters would increase dynamic compression at lower RPMs due to earlier intake closing provided by the fast bleed down. It would pull about the same at high RPM.

Increasing static compression to the mid 10s with high flowing aluminum heads is the nuclear option.

3.73 and 2004R's 2.74 first gear and a 2800 stall should let it spin up. It should blow the tires off. Surprised it feels lazy. How much timing at idle? Did you and cliff discuss secondary opening speeds?

Knowing base timing, compression test and vacuum at idle would help us understand what it's doing now.
